Rare
Under 5% of wildlife watchers report an Urbane Digger Bee sighting in Los Angeles on a given day, based on 205 verified sightings from GBIF citizen-science data. It is the 110th most-seen of the 851 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
July to October
In those months about 10% of wildlife watchers report an Urbane Digger Bee in Los Angeles on a given day, against under 5% in November to June, the lowest months. Those are among Los Angeles's driest months, with about 5 mm of rain a month against 75 mm in February.

Across all the parks we cover, that three-hour window holds the most Urbane Digger Bee sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 6 cities where we can rate Urbane Digger Bee sightings, Los Angeles ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Sacramento (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Urbane Digger Bee is recorded against all the insects logged in Los Angeles (205 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
